In practice, usually the entire system is initially assembled and checked, and
only after that 230 VAC power is supplied. Sometimes this process takes time.
If there is no delayed start function, then after connecting the battery, the switch
and cameras will start working immediately. Loads will gradually discharge the
battery to a safe voltage. Deep discharge is prevented. However, when the
battery is half-discharged for a long time, its capacity will drop. To prevent this,
the delayed start function was implemented.
If you need to force start the switch operation from the battery in the absence of
external power supply, you may use the cold start function. To do that, short
press the START button. The switch will start. To deactivate the switch, you
should disconnect at least one battery.
3.9.5 Battery function check
Battery capacity is the amount of electricity given by a fully charged battery until
it is discharged to reach the final voltage. Battery capacity changes throughout
the service life. During operation, the capacity remains stable for a while, and
then begins to gradually decrease (residual capacity).
Residual capacity can be estimated by special devices (battery capacity
testers). It is recommended to check the battery condition once a year. Using a
battery with low residual capacity reduces the uninterrupted operation time of
the switch.
Switch batteries operate in the floating mode. The service life of the batteries if
supplied in this kit is 5 years under normal conditions. When the switch
operates with frequent power outages or in hot weather conditions, the battery
degrades more rapidly. If it is not possible to test the battery as described
above, we recommend replacing the battery every 2 years.
